The fiscal deficit target for the current fiscal year is "daunting", Finance Minister Arun Jaitley told lawmakers in parliament on Friday.
Jaitley has promised to narrow the deficit to 4.1% of gross domestic product in the year to March 2015 from 4.5% a year earlier.
However, many private economists have dubbed the deficit target rather optimistic, citing weak tax receipts in a sluggish economy and high government expenditure commitments.
